</dependency>

編寫bean的xml描述文件。名稱隨意。

<?xml version="1.0" encoding="utf-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
    <bean id="sysoAction" class="spring.sysoAction">
        <property name="ss" ref="syso"></property>
    </bean>
    <bean id="syso" class="spring.syso"></bean>
    <!-- more bean definitions go here -->
</beans>

syso類

package spring;

public class syso {

    public void test(){
        System.out.println("test");
    }
}

sysoAction類

package spring;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class sysoAction {

    syso ss;

    public syso getSs() {
        return ss;
    }

    public void setSs(syso ss) {
        this.ss = ss;
    }
    public void test(){
        ss.test();
    }
    public static void main(String [] args){

        ApplicationContext ctx=new ClassPathXmlApplicationContext("SpringBeans.xml");
        sysoAction s=(sysoAction) ctx.getBean("sysoAction", sysoAction.class);
        s.test();
    }

}

執行成功後會輸出 test
